Best practices for monitoring CDN logs

Content delivery networks (CDNs) store copies of content in geographically distributed servers to extend the reach of applications without sacrificing performance. CDNs reduce demand on individual web hosts by increasing the number and regional spread of servers that can respond to incoming requests for cached content, enabling faster delivery of web content and a better experience for end users. They are ideal for delivering content requiring large amounts of data transmission, such as music or video streaming. Additionally, CDNs help reduce the impact of network attacks by decentralizing web processing and enabling quick re-routing of traffic. Monitoring CDN logs can provide critical insights into system health, including issues in resource utilization and network security. CDN logs catalog information about incoming and outgoing web requests, helping determine who is visiting an app, how often they visit it, and what they access when they are there. They also include information about request performance, such as processing time and response size. Datadog provides features to aggregate, visualize, and correlate CDN logs alongside metrics and traces from the entire system, enabling users to see all their data in one view.
